The whole range of Elmark sockets is satisfactory. The only point one should pay attention to when installing them is the screw that adjusts the frame to the wall piece of the power socket, because if it tightens too much, it cracks the base. Simple tightening without force and all is well. The quality of the plastics is good, while the sockets and switches themselves work very well. In graphite color (if it matches your aesthetics and the shades of your walls) it has the advantage that it does not yellow over time and adds a touch of modernity to the home. As for the dimmer, it is responsible for the 3 stars. The circuit is not of good quality, resulting in it breaking within 1 year or a little more. I have already changed the dimmer model, after 2 such dimmers that I purchased broke. (Pay attention to the connection, do not make it under tension, because if a short circuit occurs, even if the relay opens the circuit, the dimmer will break. It will function as a simple switch without regulating the voltage.)
